I've put up my own shelves with proper brackets. But I see these
"floating shelves" advertised. I thought, "What's holding them up?"

There is usually rods that go into the wall. Can be a bit fiddly to
get them in the right place so they slide into the shelf properly.

Apparently there's no right angle involved, just a screw
going straight into the back of the shelf out of the wall.
How can that possibly support anything?

It's a decent sized pair of rods that stick out of the wall
that slide into holes in the shelves with most of them.

But proper shelves have an angled bracket which can hold a lot of
weight.

But plenty don't need to hold a lot of weight and prefer the cleaner
look of a floating shelf which has no visible brackets at all.

Nothing without a 45 degree support can hold weight.

That's wrong too. I do mine that need to hold a lot of weigh
with a floor to ceiling rectangular welded frames made of
dexion slotted tubing with shelves that are fully adjustable
on 25mm spacings with the frames bolted to the walls.

So is there anything holding up the shelf apart from at the back?

Wrong, I said it's a RECTANGULAR frame, so the is one vertical at the
back of the shelf and another at the front at the front of the shelf.

So real shelves, not this floating ****. Something needs to hold the weight at the front of the shelf, or immense forces appear at the back.


To support the shelf properly, you should build support all the way down to the buildings footings.

Not required, the wall does that. All you need is to make the bracket not bend from 90 degrees to the wall.
